Ok so Software Update told me to upgrade to iTunes 11 and I did, not realizing how different the new layout is and I wanted to go back. So, I followed the directions for downgrading it back to iTunes 10.7. It worked, but the problem is that I kept getting this error:

An unknown error occurred -42408

I would get this error everytime i start iTunes

At first I really didn't think it'd be an issue because iTunes still worked fine for me and the errors i saw it for people were regarding the iTunes store and I never really use the iTunes store, BUT, when I delete a song, it ALWAYS asks me whether to keep the file in the itunes media folder or to delete it, and when I delete a song it doesn't do that anymore, so I really want to fix this issues.

Does anyone know how to get rid of it?

Update: It also claims that my iPod is broken when my computer says it works fine.

re-installed iTunes 10.7 using Pacifist (if it asks to Replace or Update on files, you want to replace). Revert to your previous library file (iTunes Library.itl)... also run disk utility and repair permissions after that.

I tried doing that, but what would Pacifist do and how would it make a difference in my situation.

I did disk utility and revert to the previous library file. and that didn't do anything.

That is correct, so remember in Pacifist to click Replace and not Update. I got back to iTunes 10.7 with no problems.

Wow!
This was the ONLY solution that helped on this issue regarding reverting back to v.10.7.0.21 after installing the HORRIBLE iTunes 11!
I THANK YOU so much for this post on installing "Pacifist" and then re-installing v.10.7.... and "Replacing" every file etc.

Hi, I have the same problem!! Now I have iTunes 10.7 but when I open it say "An unknown error occurred (42408)"

1. Mount the iTunes 10.7 dmg
2. Launch Pacifist
3. Click Open Package and navigate to "Install iTunes" package in the mounted dmg. Pacifist will open it and you will see it's contents in a window.
4. Click on the first item in the list "Contents of Install iTunes" to select it.
4. Click the Install arrow in the top right menu bar of Pacifist.
5. It should prompt you for PW
6. From there on it will install, and you just need to click Replace when prompted (replace or update).

I recommend checking and repairing permissions afterwards with Disk Utility.

Brilliant, many thanks. Now happily back to 10.7 where I will be staying. My version of 11.0 was continuously crashing after being open for 5 mins or so but just sitting idle. After the tenth time the only way was back!! I don't know how to read crash logs but it seems to have something to do with the audio codecs.

However, as others have mentioned, crashing apart - the GUI is astonishingly bad for an Apple product. The interface is something I was more used to from freeware windows programs! The new ideas are nice but the look just sucks. Is this what we have to expect from Apple now that Steve is dead? First it was iOS6 and now this!!

Initially I was unable to remove iTunes 11 as an error message would pop up saying it cannot be removed as it's needed by the OS, dragging it into App Cleaner didn't work either. So I clicked Get Info and noticed there was a "custom" rule at the top of the permissions list. So I simply changed all the permissions to Read & Write and was then able to manually delete it.

Then I downloaded a fresh 10.7 dmg (google and you'll find it) and ran that with Pacifist. Select "Open Package" then the Install arrow at the top left of Pacifist. Click "replace" with all the pop ups that appear. Then replace the .itl file with the .itl file from the "Previous Libraries" folder and finally run Disk Utility and select "Repair Permissions". You'll see a lot of files the DU changes permissions on and mine took around 5 minutes to complete.

I had to do this as initially I'd just tried re-installing from the 10.7 DMG without Pacifist and was getting the same (-42408) error messages.

Yeah but you really shouldn't have to do all that to cover apple's a--. It's not like they had to rush out 11; they've had many years of practice so this turd is completely inexcusable.

I expect bloated, non-intuitive garbage like this from windoze. I guess apple is becoming another microsoft.

You can use AppCleaner (I did that myself) but you have to go into it's preferences and un-tick "Protected default apps" (I would re protect after your done). Do not allow it to trash the user/music/itunes folder if that shows in the list (this is where your iTunes data and library/s reside).

no-idea, not sure how to help you since you first went back to iTunes 10.6.3. This reinstall works for 10.7 since it was the last version apple released before v11 of iTunes and some system files maybe different between 10.6.3 & 10.7.
